Highly textured polycrystalline fibres of monoclinic P21/c Nd2SiO5 and hexagonal P63/m Nd9.33(SiO4)6O2 phases were obtained by Laser Floating Zone in air from stoichiometric mixtures of Nd2O3 and SiO2 changing the pulling rate from 10 to 400 mm/h. Distribution of phases barely varied due to the incongruent melt of the Nd2O3:SiO2 system, resulting in fibres adequate for microwave devices owing to the dielectric character of the Nd2SiO5 phase. Raman analysis was performed in this material for the first time.

空气中激光浮区对Nd 2 O 3:SiO 2体系的处理

通过在空气中从空气中改变Nd 2 O 3和SiO 2的化学计量比的混合物,通过激光浮区获得了单斜晶P2 1 / c Nd 2 SiO 5和六角形P6 3 / m Nd 9.33(SiO 46 O 2相的高织构多晶纤维。牵引速度从10到400 mm / h。由于Nd 2 O 3:SiO 2体系的熔融不完全,相的分布几乎没有变化,由于Nd 2 SiO 5的介电特性,导致了足以用作微波设备的纤维相。首次在这种材料中进行拉曼分析。
